VAC - S38 High Performance Valve Spring & Retainer Kit
$999.95Purchase VAC - S38 High Performance Valve Spring & Retainer Kit
Our Spring Kits feature a custom dual spring capable of turning 12,000 RPM for that added piece of mind (Over-rev/Mis-shift). Our springs are shot-peened for stress relief and interference fit to control harmonic resonance across the rev range. Also in our dual spring configuration, should something happen to one spring, the other can prevent the valve from dropping and causing catastrophic engine damage.
These springs are capable of handling much higher lift for even the most aggressive of cams like our VAC S38 Race Cams! We can provide all setup data for your engine builder as well.
After rigorous testing in our engines for year after year, these Valve Springs still tests within 2% of their original rate.
From the reliable and winning results of thousands of these valve springs, we can say confidently they are the best valve spring available for your BMW at any price.
This kit includes:
- 24 High Performance Dual Interference Valve Springs
- 24 Steel Alloy or Titanium Valve Retainers
- 24 Spring Seats
- All Parts are MADE IN USA
VAC Tech Note:
Due to the nature of Titanium, Ti retainers are only recommended for street use in a S38 valve train that will be inspected from time to time. Steel is a great choice for a street, track or racing S38 powered car and you can chose to add our Performance Solid Lifter kit for the lightest, highest performance and most reliable valve train.
